If you can use ethernet get one that you can hard wire, like the Ultra. I have 2 streaming sticks (not the plus) that work great over wifi.
I have the 2017 Roku Streaming Stick (Model 3800X). Not too much problems. Less sluggish than my old FireTV stick. Use the 5GHz WiFi band for streaming, not the 2.4GHz.
I personally love my Roku 3. I have never had an issue
with the connection to my wireless, no buffering.
The picture is crisp and the remote is extremely responsive.
I'm not sure of the others but my remote has a plug for earphones which
can come in very handy (it comes with the earbuds! )
